To find the value of a, you need to equate the given expression to the equivalent expression and solve for a.
a(x+3) = 7x + 21
To eliminate the parentheses, you can distribute a to both x and 3:
ax + 3a = 7x + 21
Now, you can equate the coefficients of x on both sides of the equation:
a = 7
Therefore, the value of a that would make the expression a(x+3) equivalent to 7x+21 is a = 7.
What value of a would make the expression a(x+3) equivalent to 7x+21 ?(1 point)
